Using Probabilistic Terrorism Risk Modeling for Regulatory Benefit-Cost Analysis: Application to the Western Hemisphere Travel Initiative in the Land Environment

This article presents a framework for using probabilistic terrorism risk modeling in regulatory analysis. We demonstrate the framework with an example application involving a regulation under consideration, the Western Hemisphere Travel Initiative for the Land Environment, (WHTI‐L). First, we estimate annualized loss from terrorist attacks with the Risk Management Solutions (RMS) Probabilistic Terrorism Model. We then estimate the critical risk reduction, which is the risk‐reducing effectiveness of WHTI‐L needed for its benefit, in terms of reduced terrorism loss in the United States, to exceed its cost. Our analysis indicates that the critical risk reduction depends strongly not only on uncertainties in the terrorism risk level, but also on uncertainty in the cost of regulation and how casualties are monetized. For a terrorism risk level based on the RMS standard risk estimate, the baseline regulatory cost estimate for WHTI‐L, and a range of casualty cost estimates based on the willingness‐to‐pay approach, our estimate for the expected annualized loss from terrorism ranges from $2.7 billion to $5.2 billion. For this range in annualized loss, the critical risk reduction for WHTI‐L ranges from 7% to 13%. Basing results on a lower risk level that results in halving the annualized terrorism loss would double the critical risk reduction (14–26%), and basing the results on a higher risk level that results in a doubling of the annualized terrorism loss would cut the critical risk reduction in half (3.5–6.6%). Ideally, decisions about terrorism security regulations and policies would be informed by true benefit‐cost analyses in which the estimated benefits are compared to costs. Such analyses for terrorism security efforts face substantial impediments stemming from the great uncertainty in the terrorist threat and the very low recurrence interval for large attacks. Several approaches can be used to estimate how a terrorism security program or regulation reduces the distribution of risks it is intended to manage. But, continued research to develop additional tools and data is necessary to support application of these approaches. These include refinement of models and simulations, engagement of subject matter experts, implementation of program evaluation, and estimating the costs of casualties from terrorism events.

Forced to work and liberated from work

The work-welfare nexus is essential in all social policy regimes. The question is in what situations individuals should be entitled to social welfare benefits and in which situations they should be obliged to work. Social welfare law and administrative practices define mechanisms that separate the deserving poor from people able to work. This article analyses the functions and character of these "separation mechanisms" in Sweden during three periods in history: a) in rural society in the late 19th century; b) in industrial society during the successful years of the Swedish model from World War II until the late 1970s; and c) the present, including the period of welfare retrenchment and reconsideration since the early 1980s. The conclusion is that Swedish social policy has always been strongly work-oriented, but the specific form and content of the work ethic has varied under the influence of different ideologies and handled in different social policy institutions. Under specific conditions the work line has been either generous or restrictive and it has been based on structural attempts to improve the opportunities to work as well as on attempts to strongly pressure the individual to work. The work line of today is seen as an interesting attempt to combine an effort to create good work through improved work conditions and an effort to reinforce elements of work enforcement in the social insurance system.     

我国国家公务员社会保障制度研究综述

我国国家公务员社会保障制度推行十多年来,对稳定公务员队伍,提高政府的工作效能发挥了重要作用.但随着经济体制改革和政府人事制度改革的不断深化,这一制度在运行过程中也出现了一些需要急待解决的问题.通过对现有关于公务员社会保障制度研究的文献资料进行整理和分析,提出了公务员社会保障制度研究需要进一步深化的几个问题.     

我国征地补偿制度的问题及其完善

农地征用过程中出现的种种矛盾和侵害农民合法权益的现象反映了我国现行征地补偿制度存在的主要问题——征地补偿方式违背市场基本规则、农村土地财产权受到侵犯和征地补偿方式违背帕累托最优原则。基于对现实和理论的深入分析,本文指出我国农地征用补偿应遵循地价形成规律,并努力探索集体土地流转,合理分配土地收益,同时建立起失地农民生活和就业保障机制。     

论电话监听的合理性及其限度

电话监听是技术侦查手段的一种。适当运用电话监听,能够提高对抗犯罪的效能。然而,电话监听具有对公民隐私权、言论自由权等权利造成侵害的很大的危险性。因此,既要认识到其合理性,又要对其适用确定必要的限度,并在运用过程中,保障犯罪嫌疑人、被告人的基本人权和诉讼权利。

社会转型中农民工社会保障问题探析

加快城市化进程首先是加快人口的城市化进程,而人口的城市化首先要解决的是农民工问题.建立农民工社会保障制度是我国社会结构转型的需要,它兼顾了公平与效率,是社会保障制度改革的长期目标,也是构建和谐社会的先决条件.     

关于有效促进社会公正的几个问题

本文认为:(1)为了顺利地推进改革,为了中国社会经济持续、有效和健康的发展,就必须适应新的历史条件,顺应民意、顺应现代社会的基本趋势,把社会公正放到一个突出的位置。(2)在中国现阶段应当开始建立一个初级的社会公平保障体系。初级社会公平保障体系的基本特征是低水准、广覆盖、有实效。对于国家来说,近期需要做的事情可以分为两大块,一是国家的直接投入,二是国家的立法、监督、执行和引导。(3)有一些根深蒂固的观念在妨碍着我们重视社会公正问题。这些观念主要包括:“原始积累不可避免”,“国家财力不足”,“重视公正便会妨碍效率”,因此我们必须对这些观念进行一番必要的反思。(4)要想构建一个公正而和谐的社会,就必须培育一个庞大的中等收入者人群,形成一个“两头小,中间大”的橄榄型的社会结构,那么社会就会变得越来越稳定了。     

考虑实体店公平关切的制造商线上入侵策略研究

在单一线下模式销售的基础上,考察制造商以转销模式进行线上入侵和以代销模式进行线上入侵这两种模式,通过数理推导和数值仿真得到的研究结果表明：（1）当实体店具有公平关切心理时,制造商进行线上入侵总是有利的。（2）当消费者对线上渠道接受程度较高且实体店公平关切程度较低时,制造商将以转销模式进行线上入侵;当消费者对线上渠道接受程度较低时,制造商会以代销模式进行线上入侵,并不受实体店公平关切程度的影响;而当消费者对线上渠道接受程度适中且实体店的公平关切程度较高时,制造商倾向于以转销模式进行线上入侵。（3）无论制造商选择哪种模式进行线上入侵,制造商的线下零售价格始终高于线上。此外,随着实体店公平关切程度的增强,线上渠道和线下渠道的零售价均会同步提高。
